kmplt : Plot Kaplan Meier curve

Description

This function plots the survival curve for the provided data set as a Kaplan Meier plot. It can only be used for visualization and returns no numeric values.

Usage

kmplt(data, title)

Arguments

data

A data frame containing at least the two columns ``censored'' and ``True_STs''. Where ``censored'' contains the censorship status of the subject as either ``0/F'' for ‘uncensored subjects’ or ``$1$/T'' for ‘censored subjects’. This information is essential to be able to plot the KM curve.

title

A string of characters denoting the title of the plot produced.

Value

A plot of the survival function ``S(t)'' against the survival times (unit-less) as calculated for the provided data set.

Details

Note that this function was intended only for visualization and does not return any numerical values as such.
